WD Cloud OS 5 is a major and fundamental security release that provides an architectural revamp of our older WD Cloud firmware and adds new defenses to thwart common classes of attacks. We recommend that all users upgrade to WD Cloud OS 5 as soon as possible to benefit from the latest security fixes. WD Cloud OS2 or WD Cloud OS3 will not receive these security fixes.
